Ngokunyuka kwesantya sophuhliso lwamashishini, iivalve zoxinzelelo oluphantsi zisetyenziswa ngokubanzi kumashishini amaninzi. Njengenxalenye ephambili kwinkqubo yokuhambisa umbane, i-valve yoxinzelelo oluphantsi idlala indima ebalulekileyo ekuqinisekiseni ukusebenza okukhuselekileyo kunye nokuzinza kwenkqubo. Nangona kunjalo, phambi koluhlu olubanzi lweemveliso ze-valve eziphantsi koxinzelelo kwimarike, indlela yokwenza ukhetho olulumkileyo luye lwaba lugxininiso lwabasebenzisi abaninzi. Eli nqaku liza kuhlalutya izinto ezichaphazela ixabiso leevalve zoxinzelelo oluphantsi e-China kuwe, kwaye unike iingcebiso ezithile zokuthenga ukukunceda uthenge iivalve zoxinzelelo oluphantsi kunye nokusebenza kweendleko eziphezulu.
Okokuqala, imiba yexabiso eliphantsi loxinzelelo lwevalvu yaseTshayina
1. Uphawu kunye nomgangatho
Uphawu kunye nomgangatho zizinto ezibalulekileyo ezichaphazela ixabiso leiivalvu zoxinzelelo oluphantsi e China . I-brand yomgangatho ophezulu weevalve eziphantsi koxinzelelo, umgangatho wemveliso, ukusebenza kunye nokuzinza kungcono, ngoko ke ixabiso liphezulu. Ngokuphambene noko, i-brand jikelele yee-valve eziphantsi koxinzelelo, ngenxa yokuhluka komgangatho kunye nokusebenza, ixabiso liya kuba liphantsi.
2. Izinto eziphathekayo
Izinto eziphathekayo zevalve yoxinzelelo oluphantsi luchaphazela ngqo ubomi bayo benkonzo kunye nokusebenza. Izinto ezahlukeneyo zeevalve zoxinzelelo oluphantsi, ixabiso liya kuba lihluke. Ngokomzekelo, iivalve zensimbi ezingenastainless eziphantsi koxinzelelo ngenxa yokuchasana kwazo kakuhle, ubomi benkonzo ende, ixabiso liphezulu kakhulu.
3. Iinkcukacha kunye neemodeli
Iinkcazo kunye neemodeli zeevalve eziphantsi zoxinzelelo nazo ziyizinto ezibalulekileyo ezichaphazela ixabiso. Iinkcazo ezahlukeneyo kunye neemodeli zeevalve eziphantsi, iindleko zabo zokuvelisa kunye nokusebenza zihluke, ngoko ixabiso liya kuba lihluke. Khetha imilinganiselo efanelekileyo kunye neemodeli ngokweemfuno zokwenene.
4. Ubudlelwane bokubonelela ngeemarike kunye nemfuno
Unikezelo lweemarike kunye nobudlelwane bemfuno bunempembelelo ethile kwixabiso leevalvu zoxinzelelo oluphantsi e-China. Xa imfuno yemarike iphezulu, ixabiso lisenokunyuka ngandlel’ ithile; Imfuno yemarike incinci, kwaye ixabiso lisenokuba liphantsi.
Okwesibini, iingcebiso zokuthenga
1. Khetha uphawu oluchanekileyo kunye nemodeli ngokwemfuno yokwenene
Ekuthengweni kweiivalve zoxinzelelo oluphantsi , kufuneka idibaniswe neemfuno zangempela zokusetyenziswa, khetha uphawu oludumileyo olunomgangatho omhle kunye nokuzinza. Ngexesha elifanayo, imodeli efanelekileyo kunye neenkcukacha kufuneka zikhethwe ukuhlangabezana neemfuno ezithile zenkqubo.
2. Nika ingqalelo kwizinto eziphathekayo, nikela ingqalelo ekusebenzeni kweendleko
Xa kuthengwa iivalve eziphantsi koxinzelelo, kufuneka sinikele ingqalelo kwimpembelelo yezinto eziphathekayo ekusebenzeni kwemveliso kunye nobomi. Ngelo xesha, phantsi kwesiseko sokuhlangabezana neemfuno zokusetyenziswa, kufuneka siqwalasele ngokupheleleyo ukusebenza kweendleko kwaye sigweme ukulandela ngokungaboniyo amaxabiso aphantsi.
3. Nika ingqalelo kwinkonzo emva kokuthengisa kunye nomgaqo-nkqubo wewaranti
Xa kuthengwa iivalve eziphantsi koxinzelelo, kuyimfuneko ukuqonda inkonzo yomenzi emva kokuthengisa kunye nomgaqo-nkqubo wewaranti. Umgangatho ophezulu wenkonzo emva kokuthengisa kunye nomgaqo-nkqubo wewaranti unokuzisa ukhuseleko olungakumbi kubasebenzisi kunye nokunciphisa umngcipheko wokusetyenziswa.
Ngamafutshane, ekuthengweni kwe-liivalvu zoxinzelelo , kufuneka siqwalasele ngokupheleleyo uphawu, umgangatho, izinto eziphathekayo, ukucaciswa, iimodeli kunye nezinye izinto, ezidityaniswe neemfuno zangempela, khetha iimveliso ezingabizi kakhulu. Ngexesha elifanayo, nikela ingqalelo kwinkonzo emva kokuthengisa kunye nemigaqo-nkqubo yokuqinisekisa umgangatho wokuqinisekisa ukuba iivalve ezithengiweyo ezinoxinzelelo oluphantsi zinokuhlangabezana neemfuno zokusetyenziswa kunye nokunciphisa umngcipheko wokusetyenziswa.
